= Bytekit = == What is Bytekit? == Bytekit is a PHP extension that provides a userspace representation of the opcodes generated by the Zend engine compiler built into PHP. This extension provides not only access to the raw op_array data but also contains a Zend engine disassembler that exports control flow information in form of code flow graphs and basic blocks. Bytekit is meant as a tool to understand the internals of PHP better, to debug Zend engine error cases and as base to develop all kinds of static and dynamic code analysis tools. == Download == Bytekit v0.1.1 is available for download [http://www.bytekit.org/download/bytekit-0.1.1.tgz here]. Example Graphviz Visualisation of phpBB3's viewtopic.php - main function contains 972 basic blocks - see [http://www.bytekit.org/download/phpbb3_viewtopic_php.dot here] ([http://www.bytekit.org/download/phpbb3_viewtopic_php.svg SVG] version). == Documentation == A real documentation is comming soon.
